Move to ActiveConfig Properties.

This still needs some cleanup, but works well.

I'd like some users to test (and comment here) on the following
commands:
mvm set pvp true/false (can't test this by myself)

Everything else looks good. All tests pass. Think this one (due to the
active properties) fixes #322
